Redundancy in active pixel sensors

An active pixel sensor a plurality of sensor pixels disposed in a row, a plurality of sensor pixels in a column, and steering circuitry coupled to each of the sensor pixels. Each of the sensor pixels includes a first pixel circuit, and a second pixel circuit. For each of the sensor pixels, the steering circuitry includes a first switch, a second switch, a third switch, and a fourth switch. The first switch and the second switch are connected in series to route an input signal to the first pixel circuit. The third switch and a fourth switch are connected in parallel to route the input signal to the second pixel circuit.
